Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an insecticidal method capable of extremely effectively erasing flies, mosquitoes, cockroaches, etc. generated in the interiors of restaurants, restaurants, kitchens, etc. and an apparatus used for the method. It is a thing.

[0002]

2. Description of the Related Art A large amount of flies, mosquitoes, or cockroaches are generated in the interiors of restaurants, restaurants, etc., and in kitchens. No effect. For such a purpose, recently, an insecticidal plate containing a synthetic resin containing an evaporative insecticide is commercially available, but this is simply hung, and the agent evaporating from the plate causes a fly,
Since it controls mosquitoes or cockroaches, it can control flies and mosquitoes near the plate, but cannot control flies and mosquitoes far from the plate, and it has little effect on controlling cockroaches.

[0003]

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and it is extremely effective in controlling flies, mosquitoes, cockroaches, etc., which are generated in the interiors of restaurants, restaurants and the like and in kitchens and the like. It is an object of the present invention to provide an insecticidal method that can be performed and an apparatus used for the method.

[0004]

Means for Solving the Problems As a result of earnest research to achieve the above object, the inventors of the present invention have noticed that air is uniformly agitated and mixed by an air conditioner, and based on the same principle as the air conditioner, a transpiration insecticide The present invention has been found to be extremely effective in eradicating flies, mosquitoes, cockroaches, etc. in a large room by mixing the air with air almost uniformly.

That is, according to the present invention, a synthetic resin contains a transpiration insecticide, which is formed into small pieces or particles and housed in a net-like container, and the room air is passed through the net-like container to circulate in the room. It is characterized by In the insecticidal device of the present invention, a net-like container is connected to one end opening of the tubular body, and a fan equipped with a rotary blade that is rotated by a motor is connected to the other end opening of the tubular body. The container is characterized in that it contains a synthetic resin containing a transpirationable insecticide, which is formed in a small piece shape or a granular shape, and allows the indoor air to pass through the mesh container by the rotary vanes and circulate in the room.

The transpirationable insecticide used in the present invention includes:
Although dichlorvos (dimethyl dichlorovinyl phosphate) and ethyl chloride are mentioned, dichlorvos is particularly preferable for the purpose of controlling cockroaches. A known method may be used to incorporate the transpiration insecticide into the synthetic resin. In the present invention, it is necessary to form the synthetic resin in the form of small pieces or particles, which is to evaporate a large amount of insecticide by increasing the contact area with air. Even if a large amount of insecticide is evaporated as described above, in the present invention, since a large amount of indoor air is mixed almost uniformly by the principle of the air conditioner, the concentration of the insecticide in the indoor air is the same as that of the conventional transpiration insecticide. The concentration is lower than the concentration of the insecticide near the insecticidal plate when the insecticidal plate containing the is used. There is no danger to the human body. For controlling small insects such as flies and mosquitoes, it is preferable to form them into small pieces, but in order to effectively control cockroaches, it is preferable to form them into particles.

Embodiments of the present invention will now be described with reference to the drawings. FIG. 1 is a sectional view showing an insecticidal device of the present invention,
It comprises a mesh container 2 placed on the upper end of the cylindrical body 1, and a fan 3 connected to the lower end of the cylindrical body 1, and the fan 3 is configured such that a rotary blade 5 is rotated by a motor 4. In the net-like container 2, a transpiration-resistant insecticide-containing synthetic resin formed in a small piece shape or a granular shape is installed.

As shown by the arrow, air flows into the apparatus from the opening at the bottom of the fan 3, passes through the mesh container 2,
It contains a transpirationable insecticide and is ejected into the room from the upper end of the device.
It circulates in the room and flows into the device again. In the above-described embodiment, the mesh container 2 is formed of a wire mesh and has an open upper end. However, when the synthetic resin is formed into fine particles, the synthetic resin is prevented from soaring and scattering. It is good to cover the top with a net-like lid.

A commercially available insecticidal plate containing 18% of dichlorvos as a synthetic resin containing a transpiration-resistant insecticide is used for about 1 cm ×
Using a piece cut into pieces of 3 cm in size, the device of the present invention shown in FIG. 1 was used to kill insects of flies and mosquitoes in a dining room of 300 m ² . The device of the present invention is placed in the center of the dining room where a large number of flies and mosquitoes are flying, the rotary vanes 3 are rotated, and the air in the dining room is sucked from the bottom of the fan 3 and the air is passed through the mesh container to produce the air. Dichlorvos was contained therein, and it was ejected from the upper end of the device into the cafeteria. The operation of the device was continued for 2 hours, and air was circulated in the cafeteria by the device of the present invention. As a result, the flies and mosquitoes in the dining room were completely killed. It was also confirmed that cockroaches also appeared in the cafeteria and died.

If the device of the present invention is housed in a flower basket, several artificial flowers are placed in a net-shaped container, and the device is operated by hanging it on the wall of a restaurant or the like where customers enter, the interior feeling is excellent. Moreover, the restaurant can be kept in a state where flies, mosquitoes, cockroaches, etc. do not appear at all times.

[0011]

According to the method of the present invention, the transpiration insecticide and the air are sufficiently stirred and mixed and circulate in the room according to the same principle as that of the air conditioner. Since the mixture is uniformly mixed, there is no fear that the concentration will locally cause harm to the human body, or conversely, the concentration will locally become lower than the effective insecticidal concentration and that the insecticidal effect will not be exhibited.

[0012]

[Effect] As described above, according to the present invention, by the same principle as an air conditioner, a transpiration insecticide is mixed with air to control indoor flies, mosquitoes and cockroaches. The agent mixes evenly with the indoor air at a very low concentration that is completely harmless to the human body, so it is safe and effective for restaurants with people in the room, flies in the cafeteria, mosquitoes, and cockroaches. Can be controlled.
